Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention has a reel disk for winding and rewinding a magnetic tape, and a cassette holder, and is capable of lifting a magnetic tape cassette to an ejection position for inserting and ejecting the cassette, and a loading mechanism for lowering the magnetic tape cassette onto the cassette support in the playback position where the hub of the reel engages the take-up spindle; the cassette holder comprises two holder plates facing each other; It has a generally U-shaped section of interconnecting transverse holder walls, with one of the holder plates in the ejection position and the other of the holder plates in the regeneration position being connected to the cassette support. The present invention relates to a magnetic tape cassette device in which the cassette holder is rotatable around a spindle so as to be substantially parallel to the cassette holder.

0002

BACKGROUND OF THE INVENTION Magnetic tape cassette loading mechanisms are used in all magnetic tape cassette devices in which the magnetic tape cassette cannot be placed directly into the playback position by hand. Such a loading mechanism is described, for example, in West German Patent No. 3,717,587 (Japanese Unexamined Patent Publication No. 63-311,
652)). The cassette holder has a generally U-shaped section consisting of two flat holder plates interconnected by transverse holder walls. The cassette holder is moved up and down by a lift lever that is rotatable around an axis perpendicular to the loading and ejection directions of the magnetic tape cassette. The cassette drive is guided in a slot extending in the loading and ejection direction within the lift lever and is moved in the loading and ejection direction by the actuating lever under the control of an inwardly movable ejection rod. do.

0003

The mechanism for raising and lowering the cassette holder requires lateral guide means fixed to the chassis. Furthermore, an operating member is required for raising and lowering the holder while guiding it horizontally. This requires a considerable number of mechanical components.

DE 26 37 141 A1 describes the rotation of a cassette holder having a U-shaped cross section about an axis parallel to the longitudinal direction of the transverse holder walls. In this case, the holder plates extending from the lateral holder walls are inclined relative to each other so that in the ejection position the upper holder plate is approximately parallel to the cassette support;
The lower holder plate is formed to be substantially parallel to the cassette support in the playback position.

In this cassette holder, the cassette is not properly guided during loading and ejection.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a magnetic tape cassette device having a loading mechanism that can easily control the raising and lowering of a cassette with a small number of parts.

[0007]

To achieve this object, the magnetic tape cassette device according to the invention comprises: - providing in the region of the transverse holder wall a support ridge for movably supporting the cassette in the ejection position; - The support protrusion is movable away from the cassette, and the rear wall of the cassette is lowered to lower the cassette to the playback position.

[0008] According to this configuration, the cassette can be efficiently guided to the support protrusion when loading and unloading the deck. This support ridge supports the rear wall of the cassette in the upwardly pivoted position of the cassette holder. The support ridges form a rail on which the rear wall of the cassette slides during loading and ejection of the cassette.

According to a preferred embodiment of the invention, the support ridge is a support bend provided on the transverse holder wall. In this case, the support ridge becomes a fixed part of the cassette holder.

[0010] In a first aspect of a preferred embodiment of the invention, the support ridge is formed by a movable part, which is the support rim of the retaining spring and which rim is rotatable. Furthermore, in a second aspect of this embodiment, the movable part is formed by a rotatable support block. Therefore,
In this embodiment, the support ridges are individually manipulated parts.

Furthermore, in another preferred embodiment of the invention, - the cassette in the holder is controlled to be pressed against the cassette support in the playback position by spring action, - during lifting of the cassette, the spring The holder is configured to receive a torque due to the action and take a position not parallel to the regeneration position until the holder reaches the ejection position.

[0012] In this way, the cassette is constantly subjected to the pressure generated by the spring action and the loading mechanism is free from wobbling.

Furthermore, in another preferred embodiment of the invention, the elastic element is arranged on one of the holder plates;
Preferably, the elastic element presses the cassette towards the cassette support when the cassette is in the playback position, and pivots the cassette to the ejection position of the holder at the beginning of the lifting action. The elastic element is a blade spring arranged on the upper holder plate.

[0014] Thus, in the playback position, the spring acts as a pressure spring that presses the cassette against the cassette support with a certain pressure to prevent rattling and promote proper tape guidance. During the change from the play position to the ejection position, this spring acts to move the cassette rear wall upwardly and press the cassette against the upper holder plate.

To this end, in another preferred embodiment of the invention, the lower holder plate, which is parallel to the cassette when supporting the cassette in the playback position, is provided with a blade spring that extends upwardly towards the front of the cassette. The selected cassette support point is provided such that the force exerted by the cassette creates a torque on the cassette about the support point, which torque forces the cassette toward the support ridge. As a result, the cassette is always pressed against the upper holder plate when it is not in the playback position.

[0016] In this case, it is preferred that the support point is not on the cassette. In this way, the lower holder plate does not interfere with the cassette in the play position.

Furthermore, in another preferred embodiment of the present invention, the spindle of the holder is arranged so that when the cassette holder is rotated, the supporting fold moves away from the cassette and lowers the cassette. . According to this configuration, when the cassette holder rotates downward, the supporting bent portion comes out of the downward path of the cassette rear wall, and the cassette rear wall can assume the reproduction position.

Furthermore, in another preferred embodiment of the present invention, the return movement of the cassette to the support bending portion is performed by a return spring acting on the front part of the cassette during vertical rotation; Preferably, the spring is attached to the chassis. This configuration is extremely simple and requires no additional components since only the front part of the cassette requires guidance. Furthermore, during the injection movement the cassette is reliably guided towards the support fold.

Furthermore, in another preferred embodiment of the invention, the retaining spring of the movable part is a blade spring, the blade spring having an end attached to the cassette holder orthogonally to the spindle of the cassette holder. , configured to be movable in a direction away from the cassette by an ejection rod of the cassette device, such that a support rim connected to the retaining spring is retracted from the downward path of the rear wall of the cassette. In this case, the support ridge is retracted and the rear part of the cassette is not blocked from its downward path to the playback position.

Furthermore, in another preferred embodiment of the invention, the retaining spring has an actuating arm that can be acted upon by an ejection rod and is configured to deform the retaining spring. According to this configuration, since the ejection rod reliably retracts the support ridge or the support rim from the downward path at the rear of the cassette, the combination of the rotating position of the cassette holder and the backward movement of the support ridge frees the rear of the cassette. is obtained.

The retaining spring is constructed with a cassette rim that acts on the rear wall of the cassette when the cassette is in the play position. This arrangement improves the positioning of the cassette with respect to the sound head.

Furthermore, in a preferred embodiment of the present invention,
retaining spring, support rim, cassette rim and working arm,
shall constitute an integral piece of elastic material.

Furthermore, in a preferred embodiment of the present invention,
A retaining spring configured as a blade spring has an end pivotably mounted about an axis parallel to the spindle of the holder and retains the other end in a pocket of the cassette holder. This arrangement allows the spring to deform by a considerable amount without losing guidance.

Furthermore, in another preferred embodiment of the present invention, the support block is rotatable around an axis parallel to the spindle of the holder, is pressed in the support direction by a spring, and is magnetically activated at the ejection position. The support block forms a support ridge below the tape cassette, and the support block has a working arm through which the ejection rod rotates and ejects from the inside of the cassette holder. The structure shall be such that the descending route is not obstructed. In this embodiment, the support ridge can be retracted and the combination of the pivoted position of the cassette holder and the retraction movement of the support ridge leaves the downward path unobstructed.

Furthermore, in another preferred embodiment of the invention, the support block is arranged to press against the rear wall of the cassette under the action of a spring in the playback position. In this way,
A support block having a plurality of supports over the length of the cassette holder not only supports the cassette during loading and ejection movements, but also allows positioning of the cassette relative to the sound head in the playback position.

[0026] In this embodiment, the support block is
a nose part that moves to the lower side of the cassette or abuts the rear wall of the cassette, and a carrier for the nose part, the nose part, the carrier and the working arm being integrally injection molded; It is preferable to configure it as a piece plastic part. In this way, the support block is an easily molded plastic part.

Furthermore, in a preferred embodiment of the present invention,
The working arm is configured to engage and operate in conjunction with the working slope of the ejection rod that acts in the direction of movement of the ejection rod. According to this configuration, efficient force transmission can be obtained.

Furthermore, in a preferred embodiment of the present invention,
The ejection rod has working slopes facing each other, these slopes together forming teeth, through which the working arm moves in both directions of movement of the ejection rod, a time interval during which the downward path is not blocked. The teeth rotate the support rim or the support block so as to move out of the downward path against the action of the spring. According to this configuration, the support block only retreats from the action area during movement of the holder from the ejection position to the regeneration position and from the regeneration position to the ejection position.

Furthermore, in another preferred embodiment of the invention, the deck is provided with a locating pin that is engageable with a corresponding opening in the cassette, the locating pin engageable with the opening in the cassette ensuring proper regeneration during the downward movement. The configuration is such that the cassette is pulled forward toward the desired position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments of the present invention will be described with reference to the drawings.

1 to 3 show a loading mechanism of a first embodiment of a magnetic tape cassette device, particularly a car radio having a cassette holder 321. In FIGS. A first embodiment of this loading mechanism consists of a cassette holder 32 configured as a U-shaped sheet metal section with a lateral holder wall 322 and two holder plates 323, 324.
1 will be provided. The cassette holder 321 is the spindle 3
25, and this spindle 325
extends in the longitudinal direction of the lateral holder wall 322 . The holder plates 323 and 324 form an angle of 90° or less with each other. In the loading or ejecting position, the upper holder plate 323 extends generally horizontally. This allows the magnetic tape cassette 200 to be inserted horizontally into the cassette holder 321 (see FIG. 1). In this loading position, the lower holder plate 324 faces upward. The magnetic tape cassette 200 is supported on a ridge 327 of the lateral holder wall 322. When cassette holder 321 is lowered (rotated about spindle 325), ridge 327 rotates in the direction shown by arrow 328. During the downward movement of the cassette, the cassette is held by locating pins 341 whose shape pulls the cassette away from the ridge 327 as indicated by arrow 340 (see FIG. 2).

After the cassette has been lowered a predetermined amount, the relative movement results in the cassette 200 being no longer supported by the ridge 327 and assuming a lowered horizontal playback position. At this time, the magnetic tape cassette is supported by cassette supports 331, 331a (see FIG. 3).

When the ejection rod (not shown) moves through the slot guide (not shown), the cassette holder 321 rotates.

Attach the blade spring 332 to the upper holder plate 323. The free end 333 of the blade spring 332 is pressed against the cassette 200 of the holder 321. In the playback position of FIG. 3, the blade spring 332 is raised relative to the position shown in FIGS. 1 and 2 and applies pressure to the front portion 200d of the cassette 200. In this way, cassette 200 is securely held in the playback position.

The return spring 329 of the chassis 3 on which the cassette support 331, 331a is located presses the cassette in the direction of the raised portion 327. The cassette holder is 343
When the cassette 200 is rotated in the direction shown in FIG. 3 and raised from the playback position shown in FIG. 3 to the ejection position shown in FIG. The side holder plate 324 rotates clockwise around point Z, and the upper wall 200a of the cassette 200 abuts against the upper holder plate 323 (see FIG. 2). Thereafter, the holder 321 is rotated to the position shown in FIG. 1 in the direction shown by arrow 343 in FIG.

When the lower wall 200b of the rear portion 200c of the cassette 200 reaches the level of the raised portion 327 and the front portion is released from the positioning pin 354, the return spring 329 immediately presses the cassette 200 toward the raised portion 327. At this time, the cassette reaches the ejection position again (see FIG. 1). The cassette 200 can be pulled out from the holder 321 by a mechanism not shown.

FIGS. 4 to 8 show the second loading mechanism.
3 shows a cassette holder 348 of the first aspect of the embodiment. The cassette holder includes an upper holder plate 348a,
A lower holder plate 348b and a lateral holder wall 348c interconnecting the upper and lower holder plates.
It is constructed from a U-shaped sheet metal part. The holder plates 348a, 348b are inclined at an angle of 90° or less with respect to each other. In the loading or ejection position shown in FIG. 4, the upper holder plate 348a is located in a substantially horizontal plane. In the playback position shown in FIG. 7, the lower holder plate 348b is located on a horizontal plane. In order to obtain rotation, the cassette holder 34

is rotatable about a spindle 325 extending in the longitudinal direction. Up to this point, the cassette holders of the first and second embodiments have the same structure.

Upper holder plate 348a carries a lift spring 346 extending from lateral holder wall 348c toward lateral holder opening 348e. As shown in FIG. 4, when inserting the cassette 200 into the cassette holder 348, the lift spring 346
It engages with the front part 200d of. The ejection rod spring pushes the ejection rod outward.

In a second embodiment, the loading mechanism and cassette holder 348 has a multifunctional elastic portion 349 . This multi-functional elastic section 349 can be a flexible injection molded plastic section or a resilient sheet metal section. The multifunctional elastic portion 349 has both ends 349b
1,349b2, and between both ends there is a blade spring 349b which is strictly deformed as shown in FIGS. 5 and 6. For this purpose, the end 349b1 of the blade spring
is rotatable around a fulcrum 349e. The other blade spring end 349b2 is connected to the lateral holder wall 348c.
and a pocket 348f formed by a hook 348d. The multifunctional elastic portion 349 is operated by the ejection rod 45 and the ejection rod inclined surface 45a formed on this rod.
349c.

FIG. 4 shows the cassette 20 of the loading mechanism.
0 is inserted into the cassette holder 348 in the functional position. At this time, the rear wall 200c of the cassette is supported by the support rim 349a of the multifunctional elastic part 349. In this position, the support rim 349a constitutes a support and guide member for the rear wall 200c of the cassette. On the head side of the magnetic tape cassette, the lower wall 200b rests on the holder plate 348b. blade spring 34

FIG. 5 shows the state of the cassette holder just before the cassette 200 is lowered to the playback position. During the ejection movement (movement perpendicular to the plane of the drawings in FIGS. 4 to 7), the ejection rod 45 engages the lower surface of the working arm 349c by the inclined surface 45a, and the blade spring 34
9b is deformed, thereby causing the upper blade spring end 349
b1 rotates counterclockwise around the fulcrum 349e. At this time, the support rim 349a moves from the support position on the downward path of the cassette 200. The cassette rotates slightly clockwise, and the thicker part 200d on the front side presses against the lift spring 346 from below;
creates tension. This situation is shown in FIG. Cassette 2
The rear part 200c of 00 moves downward and the front part 200c moves downward.
d is pressed against the lift spring 346.

As the rear portion 200c of the cassette is further lowered, the cassette holder 348 rotates counterclockwise around the spindle 325. This means that cassette 2
This means that the front part 200d of 00 is also lowered to the playback position shown in FIG.
00b is placed horizontally on the holder plate 348b. At this time, since the cassette holder 348 is rotating counterclockwise, the blade spring 349 biased by the inclined surface 45a is relaxed. Rim 349d acts on the cassette rear wall and presses the cassette toward positioning pin 341. The lift spring 346 presses against the front portion 200d of the cassette 200 from above and pushes the cassette down toward the cassette support 331. This makes it possible to prevent the cassette from shaking when it is lowered to the playback position. The upper holder plate 348a assumes an angled position in front of the cassette window of the device. This prohibits insertion of the second cassette. Lift spring 346 and rim 349d ensure a precisely defined lowered position of cassette 200. In the play position, the cassette is supported by the cassette support shown in FIGS. 1-3, but does not contact holder plate 348b in the play mode.

In a second aspect of the second embodiment shown in FIGS. 8 and 9, the cassette holder 348 is comprised of an upper holder plate 348a and a lower holder plate 348b alternately connected by lateral holder walls 348c. Consists of letter-shaped sheet metal parts. Holder plate 3
48a and 348b are inclined to form an angle of 90° or less with respect to each other. In the loading or ejection position shown in FIG.
a is located in a generally horizontal plane, and the lower holder plate assumes an upwardly inclined position from the lateral holder wall 348c. Figure 9
In the playback position shown in , the lower holder plate 348
b is located in a substantially horizontal plane, and the upper holder plate assumes a downwardly inclined position from the lateral holder wall 348c. To achieve the rotation, the cassette holder 348 is pivotable about a spindle 325 extending in the longitudinal direction of a transverse holder wall 348c perpendicular to the plane of the drawing.

The upper holder plate 348a carries a lift spring 346 which extends from the lateral holder wall 348c towards the lateral holder opening 348e and extends beyond the opening 348e. When inserting the cassette 200 into the cassette holder 348, the lift spring 346 engages the front portion 200d of the cassette 200.

An ejection rod spring (not shown) pushes the ejection rod 45 outward.

The loading mechanism of the second aspect of the second embodiment includes a support block 351. This support block 3
51 has a carrier 352 constructed from a one-piece injection molded part and pivoted about a spindle 349e parallel to spindle 325. carrier 352

In the position shown in FIG. 8, cassette 348 is in a loading or ejection position. At this time, the upper holder plate 348a exists on a horizontal plane. The nose portion 354 supports the lower wall 200b of the rear portion 200c of the cassette 200. Therefore, the nose portion 354 is
When the cassette moves in and out in a direction perpendicular to the plane of the drawing, it forms a guide member that together with the free end 357 of the lower holder plate 348b forms a double guide path for the magnetic tape cassette 200.

During the ejection movement, the ejection rod 45 moves in a direction perpendicular to the plane of the drawing and deviates from this plane, for example by moving the ejection rod 45 inward by hand. Ejection rod 45
The inclined surface 45a engages the lower surface of the working arm 355, causing the arm to rotate upward in a clockwise direction against the action of the spring 356. At this time, the nose portion 354 also rotates clockwise, and the downward path 35 of the magnetic tape cassette 200
8 Deviate from. As described in the other embodiments above, the bottom surface of the magnetic tape cassette 200 is lowered onto the lower holder plate 358b, and the cassette holder 348 is also rotated clockwise. The movement of the support block 351 is shown in FIG. The ejection rod 45 is connected to the arrow 35
The inclined surface 45a moves in the direction shown by 9, and the operating arm 3

As shown in FIG. 9, the magnetic tape cassette is mounted on the lower holder plate 34 as in the other embodiments described above.
8b or onto the cassette supports 331, 331a. The nose portion 354 supports the lower side 200b of the magnetic tape cassette 200 with a support surface 362 in the loading position and the ejection position, and the pressure surface 363 abuts against the rear portion 200c of the magnetic tape cassette under the action of a spring 356. . This force, in conjunction with the pressure exerted by lift spring 346 on the front portion 200d of the cassette, accurately positions the magnetic tape cassette relative to the magnetic head (not shown).

The movement of the cassette holder 348 and the cassette 200 in this second aspect of the second embodiment of the invention corresponds to the first aspect, and in principle also corresponds to the first embodiment. Therefore, only two end positions are shown in FIGS. 8 and 9: the loading or ejection position and the playback position.
